CUT METAL PARTS

… from wire Ø 0,10 ÷ Ø 14,00 mm

thanks to CNC machine we are able to mould in 3D from wires any shapes

all size can be controled by laser sensors

possibility of ends sharpening

 

 

FLAT SPRINGS

… from metal sheets up to 5mm of thickness and  600mm of width

Production of cutting and shaped parts on manufacturing lines in small, middle or large series.

The diversity of our production presses allow us to produce springs, cut metal parts and shaped wire parts, using tools ranging from simple cutting tools to technically complex tools.
